Dometic is a brand, the type of fridge is key here - I’m guessing it’s a 12v compressor fridge.
The layout makes a difference too; front-loading fridges warm up every time the door is opened whilst a
top-loader will retain the cooled air.
The fridge should be connected to your leisure-battery. It may not have a standalone switch, so you’ll control it via the thermostat / temperature selector.
Some converters fit
Power Management Systems that disable the leisure electrics whilst driving / engine running, meaning the fridge will not get power during this time.
Some don’t, so you’ll have to ask your conversion company.
As above, turning the fridge on the day before setting off allows it to take power from the
EHU mains instead of the leisure-battery.
When fridge compressors initiate, the power surge is fairly high and this can sometimes trip MCB’s if the
LB is low on power.
Ice packs are good for getting fridges cooled quickly, them taking some of the strain that would be placed on the compressor and LB.
Be warned: camper fridges (particularly top-loaders) are very good at cooling so don’t be surprised it 5° on your fridge thermostat actually results in frozen food.
Don’t worry, we were all new at one time.
Just use the

tag query everytime you have a query as well as scrolling to the bottom of the page to see what similar threads are suggested - you’ll likely soon find your answer (along with other information that you didn’t realise you needed!)
If you find your query hasn’t been answered, it may be that no one knows the answer, or possibly that the question has been asked so many times that people have got bored of typing the same answer!
